I tried both quite a bit, and the Cobra definitely had more pull tendency for me, less distance, and not as solid a feel as the M2. The only two drivers that beat out the M2 for me were the Ping G30 LS Tec (with the marginally better Ping Tour shaft) and the Callaway XR Pro 16 with the Fuji Speeder Evo II. I hit them indoors, so that will impact the feel (which is the sound), and the Cobra has a different, hollow sound, whereas the M2 is a more solid crack. Comparatively, the M2 with the Kuro Kage was a bomber, but not as tight on dispersion as the Ping. The Callaway is as long if not longer than the M2, but slightly tighter - just not quite as forgiving as the Ping for my swing. The Cobra falls behind all three for me.
